Background

The inflating pump is also called an inflating machine, an inflating pump and an inflating machine, works through the operation of a motor, and is an inflating tool. The working principle of the inflator pump is as follows: when the motor is running and air is pumped out, the valve of the communicating vessel is opened by the atmospheric pressure, the air enters the air cylinder, and when the tire is pumped out, the valve is closed by the atmospheric pressure in the air cylinder, and the air enters the tire. The application field of the inflator pump is wide, and relates to automobiles, motorcycles, bicycles, rubber balls, rubber boats and the like.

In order to connect the inflator with an object to be inflated, such as a tire, an air nozzle is usually disposed at an end of an air tube of the inflator, and when the inflator is used, the air nozzle is hermetically connected with the object to be inflated, such as the tire, so that air in the inflator enters the object to be inflated, such as the tire, and an inflation function is achieved.

The air tap of the traditional inflator pump is generally fixedly connected with the valve inside of the tire through threads, and the air tap and the valve inside of the tire need to rotate for many times during connection, so that the use is inconvenient.

According to the investigation, the traditional Chinese patent CN201310579560.2 entitled "air nozzle of inflator pump" comprises an air nozzle main body and an air outlet arranged on the air nozzle main body, wherein the air outlet is provided with an extrusion block connected with the air nozzle main body. When the inflatable valve is used, the air core in the object to be inflated is squeezed by the squeezing block to open the valve port of the object to be inflated, and then air in the inflator enters the object to be inflated through the air nozzle. This air cock has improved the inflation efficiency of the air cock of inflator pump through setting up the extrusion piece, but is not improved to being connected between the valve core of air cock and tire.

Therefore, the air nozzle structure of the traditional inflator needs to be improved, so that the inflator can be connected with inflated objects such as tires more conveniently and quickly.
